Gingipains: Critical Factors in the Development of Aspiration Pneumonia Caused by Porphyromonas gingivalis.

Aspiration pneumonia is a life-threatening infectious disease often caused by oral anaerobic and periodontal pathogens such as Porphyromonas gingivalis. This organism produces proteolytic enzymes, known as gingipains, which manipulate innate immune responses and promote chronic inflammation. Here, we challenged mice with P. gingivalis W83 and examined the role of gingipains in bronchopneumonia,...

An Investigation of Antibiotic Resistance of Aggregatibacter Actinomycetemcomitans and Porphyromonas Gingivalis in Peri-implantitis Lesions

Background and Aim: It has been shown that anaerobic and capnophilic bacteria play an important role in implant failure and loss. The present study is an in vitro research aimed to investigate the antibiotic resistance of Aggregatibacter actinomycetemcomi-tans (Aa) and Porphyromonas gingivalis (Pg) in peri-implantitis lesions of Iranian pa-tients and to find laboratory efficiency of some antibi...

Molecular Mapping to Species Level of the Tonsillar Crypt Microbiota Associated with Health and Recurrent Tonsillitis

The human palatine tonsils, which belong to the central antigen handling sites of the mucosal immune system, are frequently affected by acute and recurrent infections. This study compared the microbiota of the tonsillar crypts in children and adults affected by recurrent tonsillitis with that of healthy adults and children with tonsillar hyperplasia. An in-depth 16S rRNA gene based pyrosequenci...
